Coaxial Vent Screw Placement - Baxi LUNA DUO-TEC 60 GA Notice D'installation

NOTE: Coaxial venting can run horizontal or vertical.
• Connect flue elbow to top of boiler and adjust direction of elbow to desired orientation (rear, right or left).
• Measure distance from outside wall face to elbow, this dimension will be known as 'X", add distance "Y" + 2" (50mm) to "X"
this is the total dimension of the vents. See Figure 6-5.
• Mark dimension from above on outer aluminum intake vent. Measure length of waste material, and transfer dimension to
inner grey flue pipe.
• Remove waste from both vents (flue and air). Verify cut ends are square and free from burrs. Insert flue back into intake air
vent and pass them through hole in wall.
• Check all measurements before cutting. Clearance to combustible materials is zero when using coaxial vent system.
• After installing venting use calibrated analyzer to verify there is no recirculation of combustion.
• Ensure termination is positioned with slots at the bottom.
Asphyxiation hazard. Before securing the screws ensure the pipe has been pushed in a minimum of 1-3/4" (45
mm) into the gasketed end of the other pipe. Failure to follow these instructions could result in death or serious
injury.
